To bring this app out in true DJ style, we’re warming up the crowds with live demonstrations at the Sonar electronic music festival in Barcelona, Spain. We’ve got a correspondent live on the ground to capture all the action. He grabbed some sweet shots of the demos and here’s what he had to say about his experience so far.

“We’re set up right in the middle of the main hall where all visitors go through to access the main stages. The doors to Sonar have only been open for a few hours and we’ve already seen a ton of people come through. There’s a sense of excitement as people get to use Pacemaker app for the first time — and the common word of the day seems to be ‘wow!’ People are loving how fun and easy it is to use.”

Sounds like there are definitely good vibrations happening at Sonar with Pacemaker app, now available on BlackBerry PlayBook tablet. Be sure to head to BlackBerry App World to check it out today and get busy mixing your favorite tracks.
